There was a word "Price" for hundreds of years. Then 16 years ago the PC fags decided to add "point" on the end of "Price". Same exact meaning. "The value an item could be sold at" "The monetary exchange for which an item could be bought" "The dollar range for which something could be traded".

Pricepoint always seemed like more a marketing thing to me. Something could have a price of $16.31, which is what a volume purchaser would see, but could be belong to the $20 pricepoint to which a retail customer often simplifies the price, at least at a visceral level.

I may be off here, but as I see it pricepoints are psychologically rather than mathematically significant prices, or a commonly rounded version of that price. It was mentioned in a talk at DICE 2010, that Webkins toys take advantage the fact that "to parents $12 and $20 are essentially the same amount".

Something might have a price, and other things will be set at a particular "point" where it will sell better.

DVD's might have a "price point" at 29.99 in several different currencies, and other DVDs will have a different price, say $30.05 which will not sell as well. The supply/demand tradeoff to maximise profit given a price might not work because people are illogical.
